Vibroplex

Vibroplex is the brand of side-to-side mechanical, semi-automatic Morse key first manufactured and sold in 1905 by the Vibroplex Company, after its invention and patent by Horace Greeley Martin of New York City in 1904. The original device became known as a "bug", most likely due to the original logo, which showed an "electrified bug". The Vibroplex Company has been in business continuously for 109 years, as of 2014. Amateur radio operator Scott E. Robbins, also known by the call sign W4PA, became the 8th owner of the Vibroplex Company on December 21, 2009. The company is located in Knoxville, Tennessee.
